Malik can do a certain job in 12 days. Vikram is 60% more efficient than Malik. The number of days, it takes Vikram to do the same piece of work, is.
6 and half days
7 and half days
Ratio of times taken by Malik and Vikram = 160:100
8 : 5 :: 12 : x
or 8x = 5*12 or x = 7 and half days.
the ratio is 100:160 ... why u wrote 160 :100
really i am also having confusion related to that how we u r able to write like that 160:100 how will we take ratio of time?
